The Budget depends on what we buy.
This is backwards. You make a plan, where you determine what your business needs are first, your projected needs/desires/expansion for the future, then determine what equipment purchases or rentals will be needed after.
So, one big question I haven't seen asked and answered yet: How many events per month are you providing support for currently, how big are they, and how many of these events are you able to cover with your current system?
If you've been covering 80 to 90% of your current schedule with the current inventory of equipment, and you don't have enough larger events on the horizon, you may want to stay as you are, and rent gear for the larger shows. If you've already started booking larger regular shows, then expanding the current system or buying a larger system may be in order.
If we buy a whole system beeing capable of everything we want we can do 70.000. But that`s the real upper limit. I think we will go for 50.000 if possibly.
We always rent the stage as well as the light. We can get what we need.
Okay, so let's just go with the 50k Euro figure as a budget. That is a fair budget, and may let you get a decent system for 3-4k audiences. As of today, that's about $66k USD. As Bob says, you may want to shop around locally, as other factors such as service, cross rental, and availability play into the plan. After getting quotes, then come back here for comments as Bob mentioned.
The possibility of building more subs and just purchasing top boxes with rigging and suitable coverage for the larger events is certainly a viable option.
